The invention consists in general of a valve device used in connection with an inlet and an outlet port, the valve device comprising two parts, one of which is apertured to form a assage-way between the two ports, the ot er being a closure for the same.

The inventionfurther consists'in the adaptation of the said valve device for use in con- Y nection with two inletorts, so that while one of. the parts of the va ve device is serving to form passage-way between one of the inlets and the outlet-port the other part of the valve device is seated over the other inletport to close the same.

The invention further consists in providing certain of the movable and the stationary generator below the fire-grate, and `D a common outlet leading to the carbureter.

The various connections above mentioned are not shown,as this typev of gas-making apparatus is familiar, and they are referred to merely as illustrating a particular adaptation of my valve apparatus to practical use.

The ports B fand D, it will be seen, form an interrupted passage-way, and as this passageway is inthe present instance ldesigned to lead directly from the upper part of the generator into the `carbureter these ports are lined with refractory material, as shown at B B. The opening C may or may notbe so or retort; C, a lower inlet connected with the lined. As here shown it' is not provided. I

with the lining.

The passage-way from the .inlet B to the outlet D is formed by a movable Hue-section E, the aperture forming the flue being Aalso preferably provided witha'" ireproof lining E, which, together with the' reproon' in the ports B and D, forms a continuous reproof assage-way for the gases or the like, afl ording complete protection to the .more or less destructiblev arts; of the valvel apparatus. As showng is an annulus of metal.

In the form of device Ashowniin Figs. 1 to 3, inclusive, the annular member E is connected with` a rod F, extending throu a stuffing'- box F in the top ofa bonnet formed b the upper art o the valve-casing. Astan ard G on t e top of the valve-casing'aords a bearing for the` axle G2 of the hand-wheel G3. Rigid wlth the wheel G is the spur-gear G4, which meshes with a rack G5 on an extension of the rod F. In order to facilitate the movement of the flue-section E and its associated parts, I preferably .provide the apparatus with a c'ounterbalance,` which is here shown as comprising a weight H. at `the end of a lever H ivoted'to the rod F at H2, this lever being lcrumed on 'the link H3, which is ivoted' at H4 to the lever and at H5 to the sta'n ard G. When the parts of the apparatus are-in the osition shown in Figs. land 2, the lower inlet C is closed b a disk valve J of any desired construction, tiilis valve being provided with lugs J J connected, b means of the rod J 2, with lugs E E2 on the ue-section E. It will be seen, therefore, -that when `the flue-section 'shown in'Fig.I 3, the arrowsdenoting t e path of the gases. In order to hold the section E and the valve J firmly in proper relations in the apparatus, I have provided anumber of coaoting Wedges or cams arranged on lthe 'movable parts and upon the valve-casing.

The annular member E when in the position between the ports B and D, is seated against the valve-casing by means of the wedges KK on the annular member,-Which come into contactwith wedges K K' von the sides of the valve-casing, Aas shown in Figs. 1 and 2.' K The lines.

valve J in such case islforced against the seat through the agency of the Wedge on the valve and the wedge K3 on the valve-casing. On, the periphery of the valve J are the wedges K4 K4, and when the valve is raised to close the uppler port thesewedges come into v contact with t e wedges K5 on the casing.

In Figs. 4 to 6, inclusive, I have shown a modiiied form of apparatus Where -the fluesection and the valve are connected with` a ,rock-shaft, the two inlet-ports being arranged correspondingly. In this form of a paratus the casing is indicated by the letter Il and is provided with the inlet M, preferably lined with refractory material, as shown at M', the outlet-port N with a similar lining N', and the second inlet O. A rock-shaft P extends through a stuffing-box P into the valve-caslingand has the rectangular ortion P2 toreceive the stem Q of the ro Q', which supports thelue-section R, which, as in the other form ofapparatus, maybe ,provided with a fireproof lining, (here designatedl as R.) Th e rock-shaft P has also the rectangular part P3, over which extends the fork S of the rod S', supporting a disk valve T. The full lines in Fig. 4 show the Hue-section as completing the passage-'way between ports M and N, whilethe valve T is seated to close the port O. The dotted lines on the right of Fig. 4 show the position of the luefsection when the port M is closed by the valve. An arrangement of cams or Wedgesy somewhat similar to that shown in Figs. 1 `.to 3 holds the parts in their proper relation. On the flue-section R are the wedges U, which come into contact with the wedges U on the casing when the annular'member is 'in the position shown in full The valve T willin such case be seated by means of the wedges U2 on the valve cooperating With thewedges U3 on the casing. When the valve is in position to close the port M, the Wedges U4 U4 thereon will be in contact'with the wedges U5 U5 on the casing.

The use and operation of my device will perhaps have been indicated clearlyv enough by the foregoing. It Will be suilcient to say that when the apparatus is used to control the flow of two ,streams of gas or the like, as will be the case when it is used in a gas plant, as'above suggested, a clear passage-way may be formedfrom one flue to the other, this passage-way being lined so as to protect allthe destructible parts of the valve apparatus. When the flow of gases from this source is shut off, the other port will be simultaneously opened.
